The previous sections described how to set up and configure your network for dial access security.
Once configured and enabled, you must now supply a password to originate or answer a call.

The following examples demonstrate how to enter an Answer Access security password string and
an Originate Access password string.

Answer Access password security uses two password entry techniques: VF-side password and
DTE-side password entry. A VF-side password consists of DTMF tones and is entered by the
originating caller via the AT command set, the DCP, or manually with an attached telephone.

A VF-side password can be entered with the AT dial command. The following examples illustrate
two ways to enter a VF-side password:

ATDT5551234W12345678#

or

ATD is the AT dial command.

P and T are Pulse dial and Tone (DTMF) dial modifiers.

5551234 is the phone number.

W is the second dial tone dial modifiers.

@ is the wait for quiet answer dial modifiers.

12345678 is the 8-digit password. VF-side passwords can be from 1 to 8 digits
long and are restricted to decimal digits.

# is the password terminator character.

While pulse dial can be used to originate the call, DTMF tones must
be used for the password. This can be accomplished by using the P
and T modifiers appropriately. Refer to the Dial command in
Chapter 14, AT Command Set and S-Registers, for more on
modifiers.

A DTE-side password is entered after the modems have trained, but before a normal connection is
established. The following example illustrates how to enter a DTE-side password:

abc123

Enter

abc123 is a 6-alphanumeric character password. Characters used for DTE-side
passwords are case-insensitive. DTE-side passwords can be from 1 to 
6 characters in length.

If a valid password is entered, then the modems connect and data can pass.
